nitrocli is a program that provides a command line interface for interaction with Nitrokey Pro, Nitrokey Storage, and Librem Key devices.
The following commands are currently supported:
- list: List all attached Nitrokey devices.
- status: Report status information about the Nitrokey.
- lock: Lock the Nitrokey.
- config: Access the Nitrokey's configuration
- get: Read the current configuration.
- set: Change the configuration.
- encrypted: Work with the Nitrokey Storage's encrypted volume.
- open: Open the encrypted volume. The user PIN needs to be entered.
- close: Close the encrypted volume.
- hidden: Work with the Nitrokey Storage's hidden volume.
- create: Create a hidden volume.
- open: Open a hidden volume with a password.
- close: Close a hidden volume.
- otp: Access one-time passwords (OTP).
- get: Generate a one-time password.
- set: Set an OTP slot.
- status: List all OTP slots.
- clear: Delete an OTP slot.
- pin: Manage the Nitrokey's PINs.
- clear: Remove the user and admin PIN from gpg-agent's cache.
- set: Change the admin or the user PIN.
- unblock: Unblock and reset the user PIN.
- pws: Access the password safe (PWS).
- get: Query the data on a PWS slot.
- set: Set the data on a PWS slot.
- status: List all PWS slots.
- clear: Delete a PWS slot.
- unencrypted: Work with the Nitrokey Storage's unencrypted volume.
- set: Change the read-write mode of the unencrypted volume.
Usage is as simple as providing the name of the respective command as a parameter (note that some commands are organized through subcommands, which are required as well), e.g.:
# Open the nitrokey's encrypted volume.
$ nitrocli storage open
$ nitrocli status
Status:
model: Storage
serial number: 0x00053141
firmware version: v0.54
user retry count: 3
admin retry count: 3
Storage:
SD card ID: 0x05dcad1d
SD card usage: 24% .. 99% not written
firmware: unlocked
storage keys: created
volumes:
unencrypted: active
encrypted: active
hidden: inactive
# Close it again.
$ nitrocli storage close
More examples, a more detailed explanation of the purpose, the potential
subcommands, as well as the parameters of each command are provided in
the man
page.
In addition to Rust itself and Cargo, its package management tool, the following dependencies are required:
- hidapi: In order to provide USB access this library is used.
- GnuPG: The
gpg-connect-agent
program allows the user to enter PINs.
Packages are available for:
- Arch Linux:
nitrocli
in the Arch User Repository - Debian:
nitrocli
(since Debian Buster) - Gentoo Linux:
app-crypt/nitrocli
ebuild - Ubuntu:
nitrocli
(since Ubuntu 19.04)
nitrocli is published on crates.io and can directly be installed from there:
$ cargo install nitrocli --root=$PWD/nitrocli
After cloning the repository the build is as simple as running:
$ cargo build --release
It is recommended that the resulting executable be installed in a
directory accessible via the PATH
environment variable.
nitrocli comes with completion support for options and arguments to
them (for various shells). A completion script can be generated via the
shell-complete
utility program and then only needs to be sourced to
make the current shell provide context-sensitive tab completion support.
$ cargo run --bin=shell-complete bash > nitrocli.bash
$ source nitrocli.bash
The generated completion script (bash
specific, in this case) can be
installed system-wide as usual and sourced through Bash initialization
files, such as ~/.bashrc
.
Completion scripts for other shells work in a similar manner. Please
refer to the help text (--help
) of the shell-complete
program for
the list of supported shells.
- Due to a problem with the default
hidapi
version on macOS, users are advised to build and installlibnitrokey
from source and then set theUSE_SYSTEM_LIBNITROKEY
environment variable when buildingnitrocli
using one of the methods described above. nitrocli
cannot connect to a Nitrokey device that is currently being accessed bynitrokey-app
(upstream issue). To prevent this problem, quitnitrokey-app
before usingnitrocli
.- Applications using the Nitrokey device (such as
nitrocli
ornitrokey-app
) cannot easily share access with an instance of scdaemon/GnuPG running shortly afterwards (upstream issue). As a workaround, users can killscdaemon
after callingnitrocli
withgpg-connect-agent 'SCD KILLSCD' /bye
.
nitrocli follows the Semantic Versioning specification 2.0.0.
Its public API is defined by the nitrocli(1) man
page.
Contributions are generally welcome. Please follow the guidelines outlined in CONTRIBUTING.md.
Robin Krahl (@robinkrahl) has been a crucial help for the development of nitrocli.
The Nitrokey GmbH has generously provided the necessary hardware in the form of Nitrokey Pro and Nitrokey Storage devices for developing and testing the program.
Purism was kind enough to help development of support for Librem Keys by providing the necessary hardware devices to test on.
